Margot, Cornell University, report the discovery on July 26.3 UT of a satellite of (702) Alauda (V = 11.9) from adaptive-optics J-, H-, and K_s-band imaging with the ESO 8-m Very Large Telescope UT4/YEPUN on Cerro Paranal, Chile. The satellite was observed at two epochs on each of two consecutive nights. On July 26.265 UT, the companion was at a separation of 0".58 (projected separation about 900 km) in p.a. 20 deg. The primary-to-secondary H-band flux ratio is about 1250, yielding a diameter ratio of about 35. This is the first satellite discovered to a large minor planet of type B in the SMASSII taxonomy (Bus and Binzel 2002, Icarus 158, 146). Alauda (a = 3.2 AU, e = 0.02, i = 21 deg) has been identified as the largest member of a dynamical family (Foglia and Masi 2004, Minor Planet Bull. 41, 100; Gil-Hutton 2006, Icarus 183, 93).
